In most developmental studies the only error children could make on counterfactual tasks was to answer with the current state of affairs. It was concluded that children who did not show this error are able to reason counterfactually. However, children might have avoided this error by using basic conditional reasoning (Rafetseder, Cristi-Vargas, & Perner, 2010). Basic conditional reasoning takes an antecedent, which like in counterfactual reasoning can be counter to fact, and combines it with a conditional (or set of conditionals reflecting knowledge of how the world works) to draw a likely conclusion. A critical feature of counterfactual reasoning then is that these additional assumptions be modelled after the actual events to which the counterfactual is taken to be counterfactual. In contrast in basic conditional reasoning one enriches the given antecedent with any plausible assumptions. In our tasks basic conditional reasoning leads to different answers than counterfactual reasoning. For instance, a doctor, sitting in the park with the intention to read a paper, is called to an emergency at the swimming pool. The question, "if there had been no emergency, where would the doctor be?" should counterfactually be answered "in the park". But ignoring the doctor's intentions and just reasoning on plausible grounds one might answer: "in the hospital". Only by 6 years, did children give mostly correct answers.
在大多数发展研究中,儿童在反事实任务中可能犯的唯一错误就是按照当前的实际情况作答。研究得出的结论是,没有出现这种错误的儿童能够进行反事实推理。然而,儿童可能是通过运用基本条件推理来避免这一错误的(拉费策德、克里斯蒂 - 瓦尔加斯和佩尔纳,2010)。基本条件推理采用一个前提,这个前提与反事实推理中的前提一样,可能与事实相反,然后将其与一个条件(或一组反映世界运行方式的条件)相结合,以得出一个可能的结论。那么反事实推理的一个关键特征是,这些额外的假设要以反事实所针对的实际事件为模型。相比之下,在基本条件推理中,人们会用任何合理的假设来丰富给定的前提。在我们的任务中,基本条件推理会得出与反事实推理不同的答案。例如,一位医生打算在公园看报纸,却被叫到游泳池处理紧急情况。问题是:“如果没有紧急情况,医生会在哪里?”从反事实的角度应该回答“在公园”。但如果忽略医生的意图,仅基于合理的理由进行推理,可能会回答:“在医院”。直到6岁,儿童才大多能给出正确答案。
